Fig. 6 is a perspective view of the cutting means including the handlewith the knife blade detachablymounted therein. 1 y f My presentinvention as vdisclosed herein is particularly adapted 'for-cutting: offa desired portion o1" length of pliable sheet material, such asoilcloth, rubberized cloth, paper, and the like, from 44a supply of thematerial, such as the customary roll, bolt, pack, etc.; and vtheillustrated form of invention is particularly'suited for use with 'sheetmaterial which is put up in a roll, and from which the desired portionis extended thru the device to be cut off Vthereby from the roll.

The main and essential part of this invention as disclosed hereinconsists of the improved combination mechanism 'l of holding and cuttingmeans, whereby the'sheet material is safely held in position and thedesired portion is cut 01T therefrom in such a way asto'provide asquarecut end thereon.

In Figs, 1 and 2 of the drawings the essential mechanism 'l of thisinvention is disclosed as mounted on a rack 8 which includes'spacedstandards S connected and reinforced by cross `means ll'and diagonalmeans Il; while material supporting means I2' is mounted on top thereof,as by means of'bolts i3, to enable convenient attaching and detaching ofsaid supporting means on the standards. This supporting means disclosedincludes a trough-shaped kor dished portion l2' for supporting thesupply of material I4, which is sho-Wn in the form of a roll.

The formof rack illustrated includes a plurality of arms l5 which extendacross the standards and their ends provide curved holding portions !5disposed at the two sides of the standards; while brace members l5extend along the form shown herein, and can likewise be mounted on awall bracket or secured to the wall if desired.

In the form disclosed the means I2 hasv material engaging and guidingmeans I1 extending from the dished portion I2', which means I1 isadapted to have the desired length or portion I4 of the materialextended thereover as it is drawn from the supply I4, as best shown inFigs. 2 and 4. Said means I1 is arranged in the form of curved facemeans which is engaged by the extended portion I4 of the materialduring' the cutting operation, and this means includes an upper portionI8 provided with outer edge means I9, along which and in cooperationwith which the cutting knife travels, as is best shown in Fig. 3 and isdescribed hereafter; while a face portion extends downward from edgemeans I9 and a faceportion 2| extends horizontally outward from itslower end. Said portions 29 Vand 2I together form a curved face which isshown as trough-shaped herein; While the outer edge 'of portion 2|provides a ledge 22 which is parallel to edge means I9 andextendsftransversely or squarely across the-path of travel of theportion I4` ofthe material. Y

The desired 'portion of material, when it is first drawn from the roll,then extends over and rests on theedge means I9 and on the ledge 22 ofthe face means I1. Said ledge 22 then serves for alining or squaring thematerial as it is extended thereover, whereby to enable producing a'square cut end on said cut-off portion and likewise on the part whichremains projecting from the roll.

Means 25 is provided herein which is arranged and shaped to cooperatewith face means I1 for holding the material', and it is curved or shapedto t snugly against said face means. In this form shown the means 25includes a vertical wall portion 26 and a lower horizontal wall portion21, adapted to t closely against face portions 20 and 2l, when movedinto the holding or operative position, so as to hold the materialfirmly therebetween. A reinforcing bar 28 with a knob or handle 29thereon is mounted on said wall portions 25 and 21, and this means 25 ismovably mounted on the device, being preferably swingably mounted by apair of side arms 30 extending rearwardly and pivoted by elements 3l onthe supporting means I 2.

The movable holding means 25 may be frictionally held vertically in areleased position, as indicated in Fig. 2; but I preferably also providespecial holding elements 32 which are shown as spring pressed lugs setin the side members 33 of supporting means I2, so that these lugs willhold the arms slightly elevated diagonally, as best shown in Fig. 5, tofacilitate drawing the desired portion I 4 from the roll and extendingit between the face means I1 and the cooperating holding means 25. Theseelements 32 are yieldable so that the arms 30 can be pressed downthereover into the lower and operative position, as shown in Fig. 3.

The cutting means 35 provided herein comprises a handle 36 which can bemade conveniently from a portion of sheet metal, and it includes twospaced side portions 31 which hold the knife blade 38 therebetween, andfor economy and eiciency a safety razor blade is used for the knife, andis secured in the handle by screws 39.

This cutting means is operatively mounted on the holding means, and forthat purpose the handle portions 31 are provided with a pair ol.'oppositely extending flanges 4I, and the vertical wall portion 26 ofmeans 25 is provided with a pair of channel means 42 which are spaced toprovide a slot 43 therebetween. Said pair of flanges 4I are mountedslidably in the pair of channel means 42, and the knife blade 38 extendsthru slot 43, and is adapted to travel longitudinally of the slot andadjacent to edge I9 during the cutting operation, as indicated in Figs.3 and 4.

With this construction, the movable holding meansk 25 with the cuttingmeans 35 thereon is readily swingable upwards on pivots 3l, and isconveniently held released above elements 32, to facilitate extendingthe desired portion I4 of the material between the holding means 25 andface means I1; and when this means 25 is then pressed down into itsoperative position, the knife 38 extends thru slot 43 and is positionedadjacent edge I9, being then readilydrawn thru said slot for cutting offthe portion from the supply. The cut-off portion is then still heldsafely in place by the holding means, and is only released therefromwhen the latter is swung upwardly for that purpose. The ledgev 22 at thesame time serves as means whereby to aline the extended portion, so asto enable cutting' a, square-cut end on said portion I4 and likewise Vonthe vextending part remaining on the roll.

The material engaging face means I1 with its edge I9 and the Iali'ningledge 22,'cmbined with the cooperating holding means 25 and the cuttingmeans 35, provide the essential mechanism 1 of this invention; and thatis conveniently con-v nected with suitable supporting means I2 forsupporting the supply of material, from which 4the desired portion isextended thru this mechanism and is severed thereby.

This invention is preferably also" provided with additional aliningmeans 45 to cooperate with the ledge 22, and said means is extended atright angles to the ledge 22 and the adjacent edge I9; and in thisillustrated form said means is mounted on rack 8, by bracket means 46,and is thereby connected with said ledge, so as to cooperate therewithand facilitate alining the portion I4 relative to the cutting means, inorder to assure the provision of a square-cut end on 'said portion andalso on the remaining part extending from the roll. This member 45 ispreferably also graduated and is in the form of a ruled bar or gauge,whereby to measure accurately the portion or length of material to becut from the supply; and its upper gauge mark is set at a certaindistance from the cutting edge I9, for instance nine inches, so that thedesired length of material for said portion can readily be Ineasuredaccurately and at the same time be alined properly to provide asquare-cut end thereon.
